A NaNoWriMo term that means that you 'fly by the seat of your pants' when you are writing your novel. You have nothing but the absolute basics planned out for your novel.

This outlook towards writing is often opposed by the 'planner', who knows exactly what is going to happen, when it will happen, and where it will happen. There is often enmity between the two types of writers.

noun: one who performs a pantsing on a pantsie. Sharing the pronunciation of the German word for "armor", the pantsie believes the pantser is, in fact, some kind of Nazi fascist scum. Actually, the pantser is a sort of public defender of taste, e.g. the pantser shows the absurdity of publicly displaying one's underwear by showing even more of the pantsie's skivvies. A pantser absolutely will NEVER pants a person whose pants are worn properly; this violates The Pantser Creed (definition to follow-or not).

ike: that guy needs to be pantsed!
mike: but who can do the deed?
ike: wait a minute-i could do it! all i need to do is pull down his pants and SHAZAM!! i am a pantser.
rene descarte (french philosopher and early prankster of some repute): i pants, therefore i am.
